| Abstract: | The urea formaldehyde resin(UF) was synthesized by polycondensation.The application condition of several curing agents was investigated,and the ratio and quantity of complex curing agents was defined.During the course of the curing of the urea formaldehyde resin,single component curing agent such as ammonium chloride,dilute hydrochloric acid,dilute phosphoric acid and hydrogen peroxide and dual component curing agent such as ammonium chloride-dilute hydrochloric acid and ammonium chloride-dilute phosphoric acid were used.It was shown that both the curing time and the result were appropriate when dual component curing was used. |
